The reinforcement member is generally a sheet with a plurality of snap-tabs which snap-fit to the underside of the base.

BACKGROUND OF THE INVENTION

This application claims priority to U.S. Provisional Application Ser. No. 60/649,672, filed Feb. 1, 2005.

BACKGROUND OF THE INVENTION

This invention relates to a storage container and more particularly to a container particularly adapted for storing and transporting books.

Libraries and book stores need containers for storing and handling large numbers of books. The containers must be sturdy enough to handle the weight of the books, yet preferably as light as possible. The spines of the books should be visible in the container.

SUMMARY OF THE INVENTION

The present invention provides a container that is particularly adapted for storing and transporting books.

The container includes a base up from which extend opposed end walls and opposed side walls. A divider snap-fits to the base and end walls to partition the container into two compartments. The divider may be corrugated in order to increase the stiffness of the container. The base, end walls and side walls are integrally molded as a single piece of plastic.

The end walls may include hooks integrally formed on an outer surface thereof, for interconnecting multiple containers. For example, by interconnecting multiple containers when stored, the containers can be pushed and pulled together to retrieve them from a deep shelf. The hooks may also be used by automated equipment for moving the containers.

The container may include a reinforcement member to strengthen and stiffen the base. The reinforcement member is generally a sheet with a plurality of snap-tabs which snap-fit to the underside of the base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A storage container 10 according to one embodiment of the present invention is shown in FIG. 1. The container 10 is particularly adapted for storing and transporting books 24, such as in a library or bookstore. The container 10 includes a base 12 up from which extend end walls 14, 16 and shorter side walls 18. A divider 20 connects the end walls 14, 16 and base 12 and divides the container 10 into two rows for the books 24. The divider 20 may be corrugated with horizontal corrugations as shown in order to increase the stiffness of the container. Each end wall 14, 16 includes a pair of integrally-molded hooks 22 extending from its exterior surface. The base 12, end walls 14, 16 and side walls 18 are preferably integrally injection molded as a single piece of plastic, such polypropylene or HDPE, or other suitable material. The divider 20 may be injection molded of such materials as a separate piece.

FIG. 2 is a bottom perspective view of the container 10 with a reinforcement member 26 (FIG. 3) removed to expose the base 12. The reinforcement member 26, shown separately in FIG. 3, includes a sheet 28 from which protrude a plurality of snap-tabs 30. The reinforcement member 26 is preferably injection molded of plastic, such as polypropylene or HDPE, but could be a composite or any suitable material. Referring to FIG. 4, the reinforcement member 26 is secured to the base 12 to increase the strength and stiffness of the base 12 so that the container 10 can support a full load of books and be stacked with similar loaded containers.

FIG. 5 illustrates how the reinforcement member 26 is secured to the base 12 of the container 10. The snap-tabs 30 of the reinforcement member 26 connect to complementary snap-tabs 34 in the base 12 to connect the reinforcement member 26 to the base 12.

FIG. 6 illustrates the assembly of the divider 20 into the container 10. The divider 20 includes a tapered perpendicular tab 36 that is receivable into a complementary recess 38 at a top exterior edge of the end wall 14. At the opposite end of the divider 20, a parallel tab 46 projects from the divider 20 and is receivable in the end wall 16. A plurality of L-tabs 48 extend from a bottom edge of the divider 20 and are receivable in apertures 50 in the base 12 of the container. For assembly, the divider 20 is slid down into the container 10 between the end walls 14, 16 such that the L-tabs 48 are inserted into the apertures 50 in the base. The divider 20 is then slid toward the end wall 16 so that the L-tabs 48 are locked in the base 12, the parallel tab 46 is received in the end wall 16 and the perpendicular tab 36 is received in the end wall 14. One or more of the tabs 36, 46 and 48 may provide a snap-fit connection to the container 10. A bar code 56 or other identifying indicia may be mounted on the container 10, such as on the end wall 14 as shown.

The assembled container 10 may be connected to a similar adjacent container 10′ via the hooks 22, 22′ as shown in FIG. 7. Reference numerals for components in the similar container 10′ that correspond to those in the container 10 are appended with a prime designation. The hooks 22, 22′ of the adjacent containers 10, 10′ interlock such that the containers 10, 10′ can be pulled from their storage locations together and subsequently easily detached by lifting one of the containers 10, 10′ relative to the other. As can be seen in FIG. 7, a portion of the divider 20 fits into a slot 35 through the end wall 14 so that the perpendicular tab 36 is received in the recess 38 on the exterior of the end wall 14. The opposite end 42′ of the divider 20′ is received in a vertically-extending recess 40′ on the interior of the end wall 16′.

The container 10 can be stacked on top of similar containers 10′, 10″ as shown in FIG. 8, loaded or empty.

FIG. 9 is a top view of the container 10. FIG. 10 is a side view of the container 10. FIG. 11 is a bottom view of the container 10. FIG. 12 is a section taken along lines A-A of FIG. 9 through the container 10. FIGS. 13 and 14 are end views of the container 10. As can be seen in FIG. 14, the parallel tab 46 projecting from the divider 20 extends into an opening 54 passing through the end wall 16.
